No. The L5-S1 Intervertebral disc is the last disc in the spine because the 5 segments of the sacrum and the 4 segments of the coccyx are fused (though they are seperated from each other by a ligament).

What part of the body is the spine?
Firstly, the spine is separated into three separate types of vertebrae: the first seven starting at the base of the skull are the cervical vertebrae (and the first specifically being the atlas and second the axis), the next twelve are the thoracic vertebrae, and the last five are the lumbar vertebrae. The spine ends with the large sacrum bone and then ends with the coccyx (tailbone). between these vertebrae are disks of hyaline cartilage. The vertebral column houses the spinal cord. The spinal cord branches out between each vertebrae with nerves that lead to different areas of the body.
What are vertebrae and what is their function?
A vertebrae are bones in the spinal column (also called spine or backbone)The function of the spinal column is to protect the soft spinal cord and to support the body and hold the head upright.Plural for vertebra. Bony segments forming the human spinal column.31-33 total vertebrae (most adults have 33 total vertebrae)Cervical vertebrae (C1-C7): 7Thoracic vertebrae (T1-T12): 12Lumbar vertebrae (L1-L5): 5Sacral vertebrae (S1-S5): 5Coccygeal vertebrae: 3-5IT IS THE SMALL BONES THAT FORM THE SPINAL CORDvertebrae i a series of bones to make up the spine. A vertabrae is an animal with a back bone. There are five classes of vertabrae: amphibeans, birds, fish, mamals, and reptiles.
How many vertebrae makes up the spine?
it sometimes depends on the person, but there are roughly 33 in the average personit also depends what you count as vertabrae, as some people might tell you just 24Individual vertebrae named according to region and position, from superior to inferiorCervical - 7 vertebrae (C1-C7) C1 is known as "atlas" and supports the head, C2 is known as "axis"Possesses bifid spinous processes, which is absent in C7Small-bodiedThoracic - 12 vertebrae (T1-T12) Distinguished by the presence of coastal facets for the articulation of the heads of ribsBody is intermediate in size between the cervical and lumbar vertebraeLumbar - 5 vertebrae (L1-L5) Has a large bodyDoes not have coastal facets nor transverse process foraminaSacral - 5 (fused) vertebrae (S1-S5)Coccygeal - 4 (3-5) (fused) vertebrae (Tailbone)
What happens in s1 phase of the cell cycle?
DNA replication
What is the spinal root of the tibial nerve?
L4,l5,s1,s2,s3
What is a mild diffuse disc bulge with a small superimposed central disc protrusion at L5-S1?
Between each and every one of your vertebrae, there is a cartilage disc that seperates the vertebrae from each other. Basically, at L5 and S1 (lower back, the disc that is between Lumbar vertebrae number 5 and the first sacral vertebrae) there is a diffuse (spread out) bulge. On top of that, there is also some protrusion of the central part of the disc.
What is a small amount of bridging osteophytosis at the L5 S1 disc level?
In the space between the fifth lumbar and first sacral vertebrae, you have small bone growths developing. This is a normal consequence of aging.
Severe facet arthritis in L5-S1?
The L5 is the lowest of the vertebrae of the lumbar and S1 is the first vertebra of the sacrum. Severe facet arthritis is when the sacs between these vertebrae become inflamed and arthritic.
What is narrowing of the disk L4 5?
what is narrowing of the L4-5 disc mean and what can be done to treat it
Where are S1-5 nerves?
S1-5. These nerves enter through the sacral or pelvic vertebrae.
What disks are beginning with C2 and ending with S1 vertebrae?
none of them
What icd code should be used for s1 L5 herniated disc with s1 radiculopathy?
722.4
What does paracentral disc herniation at the L5-S1 level causing mass effect upon the left S1 nerve root mean?
It means that the disc between L5-S1 has protruded out to one side (not centrally), and is affecting (most likely compressing) the S1 nerve root which is below the level of the herniation (the L5 nerve root has already exited the IVF). From this report I am assuming you are having some sensory or motor problems in your lower limbs?!
What are the consequences of lumbarisation of the s1?
Lumbarization (US) lumbarisation (UK) refers to a spinal bone that takes on some of the appearances and physical characteristics of another type of vertebrae or spinal bone. At S1 lumbarisation means the S1 segment, which is usually, one of five fused segments making up the sacrum or tail bone, is not fully fused or attached to the rest of the tail bone. IT is a "sacral" segment that looks like a "lumbar" segment. It appears to be 6th lumbar vertebrae. It may have a disc or a rudimentary disc space. Functionally, a lumbarized S1 usually does not have all the functions of a normal lumbar vertebra. In most instances, this finding is interesting, but does not usually cause pain or disability. In some rare cases the joint may become irritated and painful due to injury.
What does this mean from an MRI L5 S1 disc space is mildly narrowed and the disc is desiccated reactive signal changes in the adjacent vertebral bone marrow?
If you had an MRI and have a mildly narrowed disc space between L5 S1, it sounds like you have a slightly herniated disc. Whenever your doctor gives you a diagnosis, it is best to ask as many questions as possible such as treatment options, pain management, etc.
What does loss of disc signal at L4-L5 and L5-S1 mean?
No
Does the lumbar vertebrae curve anteriorly or posteriorly in the L5-S1 facet syndrome?
anteriorly - toward the front.
